A massive solar storm in May 2024 gave scientists an unprecedented look at how Earth’s protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing ...

Superstorm Gannon, one of the most powerful geomagnetic storms recorded in recent years, wreaked havoc on Earth’s plasmasphere, shrinking it to a fraction of its normal size. This rare event provided ...

A geomagnetic superstorm is an extreme space weather event that occurs when the sun releases massive amounts of energy and charged particles toward Earth. These storms are rare, occurring about once ...

A super-charged solar storm known as the “Gannon event” forced the Earth’s plasmasphere—a doughnut-shaped shell of charged particles that normally envelops the planet—to shrink to roughly one-fifth of ...

Abstract: During the strongest geomagnetic storms of the last solar cycle, severe space-weather effects were observed at mid-latitudes. These effects included large-scale enhancements of the total ...

AEGIS ray-marches the magnetosphere in a single WebGL2 fragment shader. The magnetopause, bow shock, plasmasphere, ring current, magnetotail current sheet, auroral ovals and substorm reconnection are ...

Abstract Explanations of the mechanism governing plasmasphere corotation typically begin from the principle of a frozen-in magnetic field, whereby magnetic field lines drive the plasma to corotate ...

The Comprehensive Inner Magnetosphere-Ionosphere (CIMI) model is used to address the effects of two plasma sheet parameters on the storm-time ring current heating of the plasmasphere and ionosphere: ...

June 3, 2026 June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset. Mercury joins the pair to form a rare three-planet lineup, while ...

This panel will address research questions in the solar wind and magnetosphere interaction. The panel will report its findings to the Decadal Survey steering committee. The Space Studies Board shall ...
